Support for marijuana legalization continues to grow in Pa.

More than half of registered voters in Pennsylvania support legalization of marijuana, according to a new poll from Franklin and Marshall College.

Overall, 56 percent of registered voters approve. That breaks down to 75 percent of Independent voters who were polled, 61 percent of Democrats and 44 percent of Republicans. Seven percent were undecided.

It continues a near-constant rise in support since 2006, when 37 percent of Independents, 32 percent of Democrats and 12 percent of Republicans said they supported legalization of marijuana, according to the college. That equated to an overall rate of 22 percent who believed Pennsylvania should legalize marijuana.

The poll was conducted during the first month of May and is based on the responses of 639 Pennsylvania registered voters: 307 Democrats, 243 Republicans and 89 Independents. It has a margin of error of plus or minus 4.9 percent.
